The infrastructure required for data storage and processing has become increasingly feasible, and hence, there has been a massive growth in the field of data acquisition and analysis. This acquired data is published, empowering organizations to make informed data-driven decisions based on previous trends. However, data publishing has led to the compromise of privacy as a result of the release of entity-specific information. Privacy-Preserving Data Publishing [1] can be accomplished by methods such as Data Swapping, Differential Privacy, and the likes of k-Anonymity. k-Anonymity is a well-established method used to protect the privacy of the data published. We propose a clustering-based novel algorithm named SAC or the Score, Arrange, and Cluster Algorithm to preserve privacy based on k-Anonymity. This method outperforms existing methods such as the Mondrian Algorithm by K. LeFevre and the One-pass K-means Algorithm by Jun-Lin Lin from a data quality perspective. SAC can be used to overcome temporal attack across subsequent releases of published data. To measure data quality post anonymization we present a metric that takes into account the relative loss in the information, that occurs while generalizing attribute values.
数据存储和处理所需的基础设施已经变得越来越可行，因此，在数据获取和分析领域有了巨大的增长。这些获得的数据被发布，使组织能够根据以前的趋势做出明智的数据驱动决策。然而，数据发布由于实体特定信息的发布而导致了隐私的妥协。保护隐私的数据发布[1]可以通过数据交换、差分隐私和k-匿名等方法来实现。k-匿名是一种行之有效的方法，用于保护发布数据的隐私。我们提出了一种基于聚类的新算法SAC (Score, Arrange, and Cluster algorithm)来保护基于k-匿名的隐私。该方法在数据质量方面优于K. LeFevre的Mondrian算法和Jun-Lin Lin的One-pass K-means算法等现有方法。SAC可用于克服已发布数据的后续版本之间的时间攻击。为了衡量匿名化后的数据质量，我们提出了一个度量，该度量考虑了在概括属性值时发生的信息的相对损失。

The Hypertensive Disorders of Pregnancy (HDPs) are one of the main factors affecting maternal mortality globally and early diagnosis can lead to a significant reduction in maternal and fetal mortality. Preeclampsia typically occurs in the third trimester and early diagnosis is essential for maternal and fetal health. The current practice is to use blood pressure measurements to identify pregnant women with the risk of hypertensive disorders and use blood and urine analysis to further identify the possibility of preeclampsia. However, the shortage of adequate laboratory facilities in rural India is a major bottleneck in the diagnosis and management of pre-eclamptic women. The proposed solution addresses this problem by developing a device that measures all relevant biophysical and biochemical parameters relevant for preliminary screening of women with preeclampsia and which can be operated by semiskilled health workers. In the initial prototype model developed in the Arduino UNO platform, we propose a portable, and wireless device for the early diagnosis of HDPs by monitoring the blood pressure levels using the oscillometric method, measuring the creatinine and uric acid levels using a strip-based electrochemical sensor, measuring the albumin content using a fluorescence-based biosensor. A completely novel method for early detection of preeclampsia by measuring the sFLT-1/PIGF ratio also proposed. In this work, we are coming up with a proof-of-concept model as a single device to integrate the three different sensing techniques in which the electrochemical sensing and fluorescence sensing techniques of biomarkers are experimentally proved using blood glucose level measurement followed by appropriate calibration.

The Industrial Internet of Things (IIoT) is rapidly expanding. The social media, wireless communication and digitization technology growing rapidly and creating a large amount of data. For handling and processing, the large amount of data storage fog computing is an emerging solution which assist the cloud computing. Fog Computing improves the QoS provided to users with the help of cloud computing, by giving service to the IoT devices at their nearby proximity.The fog nodes' virtual machines (VMs) are in charge of processing and analysing IoT applications in real time.. One of the unsolved research issues is scaling the fog system efficiently to limit the customer requests reneging from the system.. The fog nodes are assumed to be a finite queue-dependent multi-server system in which tasks share the VMs.This paper evaluates the performance of the fog system by considering a multi-server queueing system with balking and reneging policies.

Guntur District, AP, India Guntur District, AP, India Physical systems are inherently nonlinear, and traditional methods of controlling such systems are based on a first-order linear approximation. Even though several nonlinear control design methods have been proposed in the past decades, most of these require analytical models. In contrast, artificial neural networks have been used as models for control since the paper published by Narendra and Parthasarathy in 1990. These recurrent networks are trained using the back-propagation algorithm, popular in other contexts. The principal issue was the notoriously slow convergence. More recently, an online sequential learning algorithm was proposed, which had better convergence properties. However, this algorithm applies to feedforward neural networks with a single hidden layer. We propose extending this algorithm’s applicability to networks with two hidden layers. The extension is achieved by incorporating error back-propagation. Further, we demonstrate that this novel algorithm has better convergence properties.

Cardiac monitoring devices have multiplied in the last few years, and have become instantly accessible hence leading to newer indications. 50 and more years ago, it was only used for critically ill patients, for an arrhythmia watch. The present day compact form factor, coupled with a real time online data display has now expanded indications to include identification of arrhythmias, ischaemia and QT intervals in drug trials. The current trend has been to enable longer and longer monitoring periods thus reducing the chance of missing significant arrhythmias. The cost of this is an increased waiting time for deployment and for analysis. Yet a significant number of arrhythmias may be identified with short monitoring periods of even a few minutes [1]. We present our experience with Sydäntek, from Carditek Medical Device, in office cardiology as a short term monitor. The study was undertaken in all diabetic, hypertensive and post stroke patients attending a routine cardiology clinic. Results showed unexpected bradycardia, atrial fibrillation, ventricular ectopics, ventricular tachycardia and pauses, leading to modification of medications and doses. This would have been missed with a routine 6 sec ECG which is the norm in the clinic . The report from this device is immediate with automation, analytics for 8 clinically significant arrhythmias, algorithms to detect non-usable, noisy segments, max and minimum heart rate, respiratory patterns and heart rate variability. We present the clinical implications and technical details for the automation . We propose that even short term, 30 min ECG monitoring has a role in effective and improved management of the patients.

D-Flipflops are widely used in designing various analogue, digital and mixed signals. Different shift registers, counters and other circuits are designed using D-Flipflop. To increase the battery life time and reduce the power consumption, the voltage given to the circuit have to be decreased in the Standby mode of operation. In this paper different D Flipflops are designed using techniques like 5 transistor D-Flip Flop, Self-voltage level D-Flipflop and modified SVL (Self Voltage Level) D-Flipflop and Novel sleep transistor technique. Comparisons are made between all the designs in terms of power, delay and leakage power. All the designs are designed and simulated with the help of Cadence Virtuoso in 90nm technology. The leakage power observed in Novel Sleep Transistor technique is 93.5% less than that observed in Modified SVL Technique.

A number of functional aircrafts still feature traditional cockpits with analogue gauges and dials in the modern world. In order to simplify aircraft navigation and allow the pilot to focus only on the most important information, technological intervention is imperative. This would also help minimize human error, log data and keep up with advancements in the modernization of aircraft displays. This paper has been focused on automating the task of analogue dial reading in cockpits, when there is a fixed-position camera available for capturing cockpit panel images. The Single Shot Detector Mobile Net v2(SSD) is used for gauge detection and cropping as it brings a good balance between speed and reliability. The Automated Analogue Dial Reading (AADR) system then preprocesses the detected gauges and finds candidate pointer lines that constitute the needle entity, using the Hough transform method. An optimal line depicting the pointer of the needle is then found from the lot, and the reading of the dial is obtained by associating the inclination of the needle with the dial configurations. Experimental results reveal that the cockpit gauges are detected from cockpit images with an accuracy of 98.64%, and the readings obtained are 98% accurate.

This paper presents a novel resilient secondary control for a cooperative control based AC microgrids against false data injection (FDI) attack. The prime objectives of a secondary control are voltage v and frequency ω restoration while sharing proportional active and reactive power. In cooperative secondary control based microgrid system these objectives are achieved using peer to peer communication channel. For this, an observer is developed to estimate the presence of external disturbance (FDI) in the V and ω values using distributed communication. These estimated disturbances are then rejected using disturbance rejection in the secondary control making it resilient against FDI attacks. The proposed controller accurately estimates the disturbances in the system and hence precisely handles both internal(at sensors) and external( at communication) FDIs. The proposed resilient controller is validated by simulating a four DERs based microgrid operated under different disturbances like constant and bounded FDI attacks in MATLAB/SIMULINK environment.

Modern day radars require multi-function capabilities to address the needs with growing threat scenarios. This demands systems with both short and long range detection supported with other multi-function capabilities including imaging. Conventionally, for radar applications with short range detection, Frequency Modulated Continuous Wave (FMCW) radar is one of the popular solutions. But recently, research has been conducted on using FMCW radar for long rage detection with high resolution based on photonics techniques. This is not possible with RF counterparts due to the existing bandwidth limitations and other related constraints. Few photonic techniques such as heterodyning [9] and frequency-to-time mapping have been researched upon and found out that these methods have few drawbacks like signal degradation and poor tunability. This paper proposes a novel method for the generation of large bandwidth and high sweep rate FMCW signals for long range detection based on the application requirements. The FMCW generation includes sawtooth as well as triangular chirps as per the target scenario requirements. The paper also brings out the mathematical analysis of the proposed hardware design used for the generation of the chirp signals. The analysis is supported with modelling results to obtain various multi-chirp patterns having a sweep bandwidth of 4GHz at a central frequency of 79GHz with a chirp time of 100ns. The proposed method can be extended to other fields like automobile and bio-medical applications.

Optical Wireless Communication uses free space to transmit the signals wirelessly in the atmosphere. Major delimiting factors of OWC system are atmospheric turbulence, attenuation due to FOG, Rain, Haze etc. Performance of the system is severely degraded by atmospheric losses. In this work, Gamma Gamma turbulence channel model is used for weak to strong atmospheric turbulence regime. Utilizing WDM and Spatial diversity MIMO significantly improves the performance of OWC System. WDM with spatial diversity MIMO is analyzed for different levels of atmospheric turbulence, heavy rain, Fog and Haze conditions. In dense Fog conditions, the OWC link distance up to 1200m could be achieved by using the proposed system. With using diversity technique, the Q factor, BER can be improved in the presence of strong turbulence regime and other atmospheric losses like Fog, Rain, Haze etc.
